  • I have the same car with the same "stalls in heavy traffic" DID YOU GET THE PROBLEM RESOLVED AND IF SO , HOW ???
  • jeepssuckjeepssuck Posts: 10
    If your symptoms are:
    - No check engine lights (or other lights) appearing on dash
    - Vehicle stalls with no warning; could stall while starting up, or while driving at highway speeds
    - Stalling occurs more often when engine is hot

    It's a faulty crank sensor. Auto Zone sells the part for around $50; sells on Ebay for around $20. I'm told that part can be replaced with the right tools and if you're mechanically inclined; I took my JGC to a local mechanic who replaced the sensor for $60. Ran just fine after that.

    DO NOT TAKE THE VEHICLE TO A DEALERSHIP FOR REPAIRS!!!!

    I bought a used 2006 Grand Cherokee 2 weeks ago and I will already be taking it back to the dealer for the 3rd time due to the gauges bouncing all around when I am driving at constant speeds. To give you the update so far...First time, they checked the battery and tightened up the posts, claimed that would fix the problem. Second time around they replaced the ignition switch, again claimed that would fix the problem. Since it is under warranty, I will make them check every idea until the damn thing is actually fixed. I would greatly appreciate it if someone wants to point me in some sort of direction since the mechanics at the dealership I purchased from seem to have no clue.

    I have a 99 grand cherokee 6cyl, had similar problem. Gauges bouncing, do you mean every gauge pegs to far side then goes to zero, maybe continues in this manner? That is the problem i had, also does any electronic overhead displays you have like miles per gallon, trip odometer(not the one in dash) all reset? If so, i think dealer was on right track with tightening battery posts, but when it happened again they should have replaced battery. When i had the problem i had noticed my battery gauge was reading 12.5 volts which i assumed was ok, it was in ok range of gauge, but a fully charged battery is actually 13.75 volts. Your jeep is 2006, battery is near end of life if original and may be low, good enough to start jeep, but the delicate computer acts weird with lower voltages and can cause a lot of strange electrical issues. When i replaced my battery 5 months ago, problems were all solved, so make sure your battery is closer to 14 volts than 12 volts with full load. Go to any store that sells battery's for them to test. Your battery is usually not under a warranty, but if it fails this test maybe you can complain and get one, or just shell out bucks somewhere else to buy one. Autozone will test and install free of labor charge right in the parking lot. Weak battery is a huge cause of intermittent electrical problems in grand cherokee, dealers never admit it and always look elsewhere for some reason.

    The last few months, sometimes my 97 JGC won't started after I turned the key, there is no power and I checked the battery terminal, it was good, the inside light was not on when the door was opened, but I can see the light under the hood was on, and hear some squeeky noise under the glove compartment, sounds like the relay/coil... or something trying to start or kick on... and sometime I slam the door few times I was able to start the car... It was just frustrating because it was intermitten, but the last few days it happended so often... Any suggetstions???

    1) Check to make sure that your battery terminals are clean and free of corrosion.
    2) Ensure that the battery connections are secure to the battery. Even though the hood light may be on, it may be dimly lit. Jiggle the battery connetions around to ensure that they are TIGHT!! to the terminals; you'll know that you have a good connection when the hood light is brightest.
    3) The BCM is located under the glove compartment. A common issue with the older JCG's is that the BCM contacts become corroded and cause all sorts of electrical problems. One solution is to:
    1) Disconnect the battery
    2) Find the BCM; Pull the module from it's plug.
    3) Clean the contacts thoroughly with contact cleaner. Wipe the contacts dry.
    4) Reconnect the BCM and battery.

    Good luck!
  • I have a 97 Grand cherokee. Engine light on. Replaced fuel pump, wires , rotor , cap , plugs, o2 sensor, trans sensor ( on 3rd one in one week). Was running fine after, trans sensor, engine light still on, after 02 sensor was installed trans sluggish, feels like emergency brake on. Three mechanics, no solution. Also, have a friend had same problem. No mechanic could solve it. Tranny eventually went and scrapped it. There's an answer for everything in this universe. What's this one? (tranny was running fine before 02 sensor, although idling a little rough, sometimes hard to start) The last mechanic said he's not getting a reading from something and he can't get a diagnosis on the scanner—mentioned possible govenor problem in trans. Anyone got the inside skinny on this problem, sounds like it's not only me??

    Best,

    I just ran into this problem, and for my situation, it was the the rear hatch. there was a short (Open) in the housing for the rear latch assy. IF it's no bother to you to have ALL your electronics working, you can disconnect the harness, and be on your way, but in my situation, I had the rear hatch assymb. replaced and of course it's a dealer part, so they soaked me $200 just for the part, and it took only 30 min. to install. You might be able to find a perfectly good replacement at a jeep graveyard.

    Has anyone or can anyone help me out. My moon/sun roof has a random glitch. On occasion when I go to close the slider, it will connect with the "Saftey" bar and re open half way. when that happens I have to push to close several times before it actually completely closes. any ideas?
  • dyeomansdyeomans Posts: 2
    I have changed the battery but there is still a strange ticking sound underneath the driver's side dash. The windows or AC will not work. Radio does work. It did this about 2 months ago when I started it....the lights went crazy blinking on and off, etc. We unplugged the battery for the night and that worked. However, it did not work this time w/the new battery. Any suggestions?
  • dyeomansdyeomans Posts: 2
    The lights are flashing on and off again too! Weird!
  • berger49berger49 Posts: 3
    Just to update... I think the problem with my Jeep might actually be solved. The dealership took apart the entire dashboard and went over every connection. In doing so, they found "MULTIPLE" ground wires that were loose. They fixed them and I have had no problems since that correction has been made.
  • jeepssuckjeepssuck Posts: 10
    FYI: When the highly qualified mechanics at the dealership work on the electrical system of your vehicle,the first thing that they do is disconnect the battery. Realize that disconnecting the battery, and leaving the terminals off for at least an hour, essentially "re-boots" the electrical system. When this occurs, the electrical system will appear to function normally for a short period of time...up to 10 days.

    Obviously, this leaves everyone with a false sense of success. Just something to think about.

    Dear berger49,

    I have a problem w/ '06 JGC where the every indicator in the entire instrument panel illuniates at once while driving. Driving performance is not affected. I am not positive what the gauges did. Did you see this problem? I am glad that the loose gnd repair fixed your problem.

    Dear dyeomans,

    What year is the JGC? I have an '06 and the headlights flash on and off rapidily in auto beam off mode. Are you talking about this problem with the headlights or something else. This is an infrequent occurance, however, it is dangerous. So far I can make it stop by switching to auto beam on.

    dj,

    i experienced random warning lights...typically the airbag light, the service engine light, and the traction control lights would flash on and off in addition to the tach and speedo bouncing all over the place while i was driving at a constant speed.

    It sounds like a case of battery under load having low voltage, if you have a battery gauge you may notice instead of it pointing to close to 14 volts its closer to 12 volts as you drive, logically that would seem to be ok since its still in good range on gauge, but it indicates battery is near end of life, you have a 2006, have you replaced battery lately? if not, its near end of life. The jeep computer needs a stronger voltage than just over 12, and a weak input can cause what you describe. Go to a place that sells battery' and gives free battery checks. Sears, Pep Boys, etc. Auto parts stores are cheaper, most will check voltage, if you buy battery they will install labor free, Auto Zone does this right in parking lot, you don't need an auto parts store with mechanics bays. This is a quick free test at auto zone, try it, post if it was cause or not. I had similar problems about 2 weeks before battery finally died and left me stranded, new battery fixed all issues, i had noticed battery read about 12.5 volts on gauge before failure, now it reads about 13.7 with the battery i put in 5 months ago with no repeat of problems, knock on wood.

    berger,

    Sounds like the same thing. Both cars are 2006. So far, I have only seen this problem a few times. I will remember the ground connection issue. BTW, my battery is new. Please post again should your problem return.

    Regards,

    We are having the exact same problems. What if any, did you find out about the vehicle dying. The vehicle will turn off with no warning. We have also had some a/c & heating work performed by the dealer...so did not fix the problem. The engine light is on with crazy readings and just today the indicator for check guages displayed.
  • dj_moversdj_movers Posts: 15
    OK, here is a new one that I think is more common. 2006 JGC. The power window will not completely close. When you close the window, it goes all the way to the top, then reverses and comes part of the way back down and then stops. Any ideas?

    Thanks,

    need to change the window relay for that window
  • dj_moversdj_movers Posts: 15
    tuggajb,

    Thanks, any idea where it is located? I could not find it in the 2 access panels. Maybe it is in the door???

    Thanks,

    dj
  • tuggajbtuggajb Posts: 646
    upon further reading the motors on the window of that year use current load to reverse if you have a binding in the window or tracks could cause the motor to reverse as a safety move (to prevent injury to people between the window and frame of the door ) check for binding and if not need new motor

    This problem is the Crankshaft Positioning Sensor. Common problem
  • john448john448 Posts: 2
    One of the switches to open the window on the master switch panel is broken.
    Dealer suggest to me to replace the entire master switch panel to solve the problem but this is a costly event.

    Do you know whether I'm able to replace only the switch and if not If I need to get the entire master switch panel where I can buy this (used) so I can install it myself.

    Any help is welcome as can't open the drivers window at the moment

    Regards

    John

    John: I've found Ebay to be a great place to find replacement parts for both of my Jeep GC's.
    If you can't find the part on Ebay, Auto Zone carries a great deal of electrical parts for the vehicle. Generally, you can perform an internet search on AutoZone.com to check for availability before visiting the store.
    I'm sure that I don't have to tell you that dealership repair shops tend to focus more on gouging the customer, than on doing the CORRECT job at the right price. Not everyone has access to a mechanic; I suppose that I'm lucky in the fact that there is a small vehicle mechanic's shop in the small city that I reside, and I tend to leave jobs like this to him. This may not be a difficult fix, but a sharp mechanic could probably do the job in short work, and do it right. To determine the difficulty of the job, you may want to search YouTube; there are many videos on YouTube, that range from the simple to the more difficult jobs.

    Hi tuggajb,

    One thing I should have mentioned. The work around is to roll the window up while keeping my finger activating the window switch. When the window reaches the top, I continuing holding my finger on the switch for several seconds until I hear a slight click. Then the window stays in the proper position.

    yep sounds as if the window motor is going bad draws to much power try and spray silicone lube in the window channels see if that helps reduce the drag
